Understanding DevOps in the telecom industry

DevOps is a portmanteau of development and operations, meaning an approach that emphasizes automation and integration between the IT operations and software development departments.

DevOps in the telecom domain aims to streamline the operation, deployment, monitoring, and maintenance of telecommunications systems and services, such as network infrastructure, communication platforms, and software applications. In the telecom context, adopting DevOps can speed up development cycles, enhance overall efficiency, and improve service quality.

Advantages of embracing DevOps in the telecom industry

Telecom DevOps adoption can lead to higher-quality services, enhanced agility, increased operational efficiency, and elevated customer satisfaction, enabling companies to stay competitive in a rapidly evolving industry. What does this mean for telecom operators in practice? Here are the key benefits of a typical DevOps telecom project:

Reduced time to market

The DevOps approach speeds up the deployment and release cycle and avoids bottlenecks through automating processes and collaboration between the development and operations teams. Consequently, telecom firms can offer enhanced customer experiences and maintain a competitive edge.

Increasing efficiency

DevOps practices automate repetitive tasks such as deployment, configuration, and monitoring, minimizing the risk of human error and reducing manual effort. By automating processes, efficiency is enhanced, operations are streamlined, and teams can dedicate their efforts to strategic and value-added endeavors.

Moreover, DevOps emphasizes automated testing, continuous integration, and continuous monitoring, improving the quality and reliability of telecom systems and services. By catching and resolving issues early in the development cycle, DevOps helps prevent service disruptions and reduces downtime.

Operational excellence

Telecom systems often must handle increasing workloads and scale quickly to meet changing demands. DevOps practices such as automated scaling and infrastructure as code enable telecom companies to promptly scale their systems up or down, ensuring they can efficiently adapt to evolving requirements.

DevOps also promotes collaboration and communication among teams of specialists such as developers, operators, network engineers, and telecom DevOps engineers. Through dismantling silos and nurturing cross-functional collaboration, telecommunications companies can improve the alignment of collaboration and communication, accelerate decision-making, and strengthen teamwork.

Cost optimization

DevOps practices can help optimize costs in telecom by reducing waste, minimizing manual interventions, and improving resource utilization. Companies can achieve cost savings through automation and efficient resource management while delivering high-quality services.

Challenges telcos encounter while embracing DevOps transformation

Unlocking Efficiency and Innovation: DevOps in Telecom Explained

Operators in the telecom industry may face several challenges when adopting DevOps practices. Common challenges include:

Insufficient overview of infrastructure status

From our experience, many telcos need more insight into whether their company’s infrastructure aligns with market standards and best practices to identify shortcomings.

Cloud migration

Migrating to the cloud is quite a journey for everyone engaged, from the technology and finance department to operations and procurement managers. How scalable, reliable, and agile will the new environment be after migration? What will be the cost optimization in the long run? How will DevOps for telecom help move CapEx (capital expenditure) to OpEx?

Consequently, how can you increase transparency over operational costs and operational efficiency? How can you avoid a lack of data accessibility and data management to enable more cost-effective ways of working with data?

Cost optimization (FinOps)

The challenge of cost optimization in telecom DevOps adoption also entails several subtasks. For example, telcos might need to see the scalability potential of their capacities and have a usage-based cost in terms of using cloud, or they might need more expertise related to internal cloud infrastructure. Also, telecom companies might need more transparency to predict and monitor current consumption to ensure they are within their budget.

Performance efficiency and reliability

Performance issues range from unpredicted system crashes and the inability to cope with load spikes to a lack of application and environmental performance monitoring. As a result, telcos might lose revenue or suffer reputational risks associated with poor product performance. More severe challenges may include lost or damaged data due to system underperformance.

Infrastructure governance

Telcos might need more infrastructure or application monitoring processes and, as a result, be unable to evaluate the current state of infrastructure operations. In turn, this leads to the need for a holistic view of the company’s infrastructure and hurdles to obtaining real-time insights on current performance.

Some cases of infrastructure governance include a lack of monitoring on both the development and production levels to plan application scaling and performance.

Comparing telco and IT workloads

It is impossible to copy-paste a DevOps approach, since there are significant differences between typical telco and IT workloads. Telecom workloads require extensive infrastructure customization to meet functional and business requirements.

typical devops cycle

Unlike in IT, where lifecycle management is embedded within the software, telecom lifecycle management is managed separately from the workload. Moreover, telcos, especially mobile operators, primarily deal with software packages rather than tinkering with application code.

Additionally, telcos operate within the dynamic network function virtualization (NFV) ecosystem, which entails multiple cloud management servers and frequent application versions or releases, making the workload environment more dynamic.

Evolution of the network engineer’s role in telecom DevOps adoption

Adopting DevOps in telecom profoundly transforms the work of network engineers, reshaping their responsibilities and emphasizing automation, cross-functional collaboration, and continuous improvement.

Network engineers are no longer confined to managing static network configurations. Instead, they are actively involved in developing and maintaining infrastructure as code (IaC) templates, enabling the setup of network resources and rapid provisioning. This shift empowers network engineers to respond quickly to changing business needs and efficiently scale network resources.

Furthermore, network engineers are embracing a more holistic approach to service delivery, working closely with development and operations teams. Adopting DevOps practices also means that network engineers are more involved in continuously monitoring and analyzing network performance metrics. Network engineers of today leverage automation tools to optimize network configurations in real time and detect anomalies, providing a seamless user experience and minimizing downtime.

In essence, DevOps in telecom is redefining the network engineer’s role. Today’s network engineers combine the functions of cloud engineer, release engineer, DevOps (or platform) engineer, build engineer, site reliability engineer, and DevSecOps engineer.

VNF/CNF workload onboarding automation

Workload onboarding includes two primary categories: Virtual network function as code and infrastructure as code (IaC). Virtual network functions need the management and orchestration layer with associated metadata and descriptors. Within a VNF package, which includes the VNF descriptor (VNFD), lies a comprehensive depiction of the VNF’s requisites, configuration guidelines, and lifecycle management protocols. The VNF onboarding process can be understood through a sequence of four steps.

Infrastructure as code (IaC)

Infrastructure as code represents a state-of-the-art method for managing IT infrastructure, encompassing automation of the provisioning and management of network, server, and other IT resources. This method works in parallel with scripting system configurations, enabling rigorous testing, seamless sharing, and efficient reuse and consequently diminishing the likelihood of human errors while increasing the pace and uniformity of infrastructure deployments. Infrastructure as code might have a declarative approach (defining the system’s desired state) or an imperative approach (defining specific commands to achieve the desired configuration).

Sandbox environments

A sandbox is an isolated testing environment allowing users to access files or execute programs without impacting the underlying application, platform, or system. A sandbox is invaluable for software developers assessing new code and cybersecurity experts examining potentially harmful software. Additionally, sandboxes offer a secure space for executing malicious code, protecting the network, host, and interconnected devices from harm. Employing a sandbox to identify malware presents an added layer of defense against security risks.

There are a lot of perspectives regarding the organization of an operator’s testing facility. However, in terms of cost-effectiveness, time-to-market efficiency, and risk minimization, there are three principal options:

Other DevOps strategies: Release management

Beyond the model discussed above, DevOps approaches can include A/B testing or blue-green deployment, the canary deployment strategy, and the N+K model. Let’s briefly touch upon these options.

A/B testing or blue–green deployment strategy

The blue–green deployment strategy is a fundamental DevOps approach that enhances software quality in production and facilitates the rapid rollout of end-user services. Blue–green deployment involves hosting two distinct software release versions, making it best suited for individual applications. While one version remains live, ensuring uninterrupted service to end users, the other is reserved for maintenance, verification, and testing. The inactive version is upgraded and tested without impacting the live version during system upgrades or maintenance. Once tests are completed, all live traffic is seamlessly redirected to the new version to ensure continuous delivery of updates and upgrades.

Implementing the blue–green approach necessitates two identical production environments to enable swift rollbacks and facilitate smooth transitions between software versions. Network traffic is redirected from the green to the blue environment using a DNS router after confirming successful tests and the stability of the new release. This seamless process enables uninterrupted delivery of services and updates, eliminating downtime.

However, it’s important to note that the blue–green deployment strategy is especially effective for research and development centers with a single-application focus and a fixed vertical environment. Consider also the challenges associated with:

 

Database synchronization One potential risk involves accidental changes to the database schema between production environment versions.
Delivery pipeline complexity Automation of the Blue/Green approach can be complex due to the need for two identical production environments and the intricate trigger point between the green and blue stages.
Cost and effort Implementing the blue-green strategy involves a higher overhead cost as both environments must be available simultaneously. Maintaining parallel environments also requires additional effort and resources, increasing costs.

Canary deployment strategy

The canary deployment approach can also be used in telecommunication networks. It targets a limited user group for testing the new release, allowing for bug identification and subsequent refinement. A canary deployment minimizes the impact of potential errors on a small user base during testing. Meanwhile, it exhibits longer turnaround times for releases, making it better suited for projects with relatively few iterations and less compatible with telecommunications workloads.

N+K model

In the N+K model, “N” signifies the minimum number of active service handlers necessary to meet the desired capacity. At the same time, “K” represents the additional deployed handlers for bolstering high availability in the event of handler failures. In the N+K model, each service handler is continuously active, managing traffic as a pooled resource and offering surplus capacity beyond requirements. In case of a handler’s failure within the pool, other handlers are ready to take on the additional load, seamlessly ensuring uninterrupted service. As long as the number of failed handlers remains within the limit “K,” the designed capacity is assured.
